Hey there, 
I lately had my first encounter with PULSE Muk and it was....waaaay too easy. 
The AI kinda screwed up badly and I wanted to know if anyone else has 
noticed similar effects.  
The AI ignored the field effect and rendered itself pretty useless, 
I was fighting Muk with a Sandslash, so the AI tried to get at me 
using water type moves. Not bad, ey? The thing is, due to the field effect 
the Wave "Picked up electricity" and thus had no effect on sandslash at all. 
The Muk also didn't vary its attacks, it used the same move over and over again 
hoping for super effectiveness and that was kind of a bummer because otherwise 
the fight would have been at least of medium difficulty (Use Moonlight again, I dare you, 
I double dare you). So as someone who doesn't know so much about game 
programming I've been wondering wether that can be fixed or if it even was intentional 
(like to demonstrate a failed prototype or something, dunno) and wether you have 
observed similar occasions (not necessarily against muk).
